Crypto prediction market Polymarket and Elon Musk-led artificial intelligence (AI) firm xAI — which owns X, the social media platform formerly known as Twitter — announced a partnership on Friday. Proud to announce Polymarket's partnership with X and xAI as their Official Prediction Market Partner," Shayne Coplan, the prediction platform's CEO, posted on X. "The two top truth seeking apps on the internet are stronger together," he added. "Welcome to News 2.0." The official X account confirmed the deal with a tweet of its own. At press time, no other details of the arrangement were shared. The announcement comes a day after Musk and U.S. President Donald Trump very publicly fell out over the national debt and the GOP's attempts to pass a new spending bill.
